Hi @vanflad!

Your homework 5 was really well done, I particularly like how you wrote comments inside your code to make it clear what was going on!

• Your process of filtering and removing the factors was done well, I liked how you checked to see if it worked!

• Interesting to see how you removed Oceania by changing the factor to a character...I did it another way, but you're right, there are multiple ways to approach the same problem! Your use of as.character() and as.factor() were innovative for me to read!

• Good job writing descriptions for all your processes, it helps put your code and the output in context and also helps to see whether the objective was achieved!

• Your factor reordering was done well also, I liked how you did it both manually and then also by a factor level (life expectancy).

• File I/O was done really well, I like how you compared the different formats of .csv, .rds and also dput and dget to see if the level orders are retained and what the differences were. Great job!

• Visualization: Good job exploring whether arrange() had any effect on the plot, I also found the same thing. I liked how you improved your ggplot, one suggestion would be to use a different colour scheme (such as one within RColorBrewer)?

• Your writing figures to file section was done well again, I like how you explained what exactly jpgs and pdfs ARE.

• Awesome troubleshooting links, I saved some for myself to keep in mind for later!!

Great homework, a lot of effort and your writing/plots/codes were very clear and easy to read! I like how you tried multiple methods for the same task to really explore them in depth. Awesome job :)

Cheers, Aisha

Hi @vanflad, here are some comments about your hw05:

• The first task was done correctly. You were able to successfully drop Oceania and its associated countries from gapminder. You showed an additional way to drop factor levels other than droplevels and fct_drop
• Factor reordering was also done well. I like that you showed other ways to do it and commented on each method
• Nice work with file I/O. Good explanations of the differences between write_csv and the other functions
• Other than the recoloring of the country colors and labels in your plots, reordering doesn’t have any significant effect. Rather than plotting the life expectancies of each country over time, a better plot for this section would be to plot side by side boxplots (or just plot the maximum life expectancies of each country) and then reorder the factors based on the maximum life expectancy.
• Repo is well organized and easy to navigate. Well done!

Your grade will be emailed to you at a later date.
